Always use "%lld" for formatting time_ts 

Given the following test program:
  #include <time.h>
  #include <stdio.h>
  #include <stdint.h>
  int main() {
    printf("time_t:    %d\n", sizeof(time_t));
    printf("long:      %d\n", sizeof(long));
    printf("long long: %d\n", sizeof(long long));
  }

These are output on various x86 architectures:
  x32$   time_t:    8
  x32$   long:      4
  x32$   long long: 8

  amd64$ time_t:    8
  amd64$ long:      8
  amd64$ long long: 8

  i386$  time_t:    4
  i386$  long:      4
  i386$  long long: 8

Therefore code using "%l[du]" to format time_ts produced warnings on x32
